91 y[W - ... one of the most important, and at the same time, one of the least expensive and troublesome, which we possess.
74 y[W - The areas of circles are to each other as the squares of their diameters.
36 y[W - Multiply the divisor, thus augmented, by the last figure of the root, and subtract the product from the dividend, and to the remainder bring down the next period for a new dividend.
83 y[W - To find the solidity of a spheroid. RULE. Multiply the square of the revolving axis by the fixed axis, and by *5236, and the product will be the solidity.
74 y[W - Area of a circle is equal to the area of a triangle whose base equals the circumference and perpendicular equals the radius.
104 y[W - These simple machines are the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw.
69 y[W - NOTE. — 1. As 7 is to 22, so is the diameter to the circumference; or, as 22 is to 7, so is the circumference to the diameter.
104 y[W - ... that there may be a balance between the power and the weight, the intensity of the power must exceed the intensity of the weight just as much as the distance of the weight from the prop exceeds the distance of the power.
36 y[W - ... and to the remainder bring down the next period for a dividend. 3. Place the double of the root already found, on the left hand of the dividend for a divisor. 4. Seek how often the divisor is contained...
84 y[W - ... by •5236 ; then say, as the square of the fixed axis is to the square of the revolving axis, so is the former product to the solidity.
